License Free Bands

Choosing Frequencies900 MHz

900 MHz900 MHz

Advantages:Foliage PenetratingNon-Line-of-SightLong Range (up to 20Mi.)Does not interfere with Wi-Fi systems

Cautions:Lower bandwidth compared to higher frequencies

Choosing Frequencies2.4 GHz

2.4 GHz2.4 GHz

Advantages:High bandwidthWiFi standard frequencyWill work on combination with other

frequencies

CautionsSaturated due to Wi-Fi / Wi-MaxAffected by weather

Choosing Frequencies4.9/5.8 GHz

4.9/5.8 GHz4.9/5.8 GHz

Advantages:Higher bandwidthLess interference 4.9 GHz Public Safety band

CautionsClear Line-of-sight requiredShorter range (up to 10 miles)

Spread Spectrum Technology A transmitting technique where the original signal is spread over a spread over a wider areawider area than is required for the data to be sent.

Benefits:Benefits:– Higher throughputs and less bit errors

• Direct Sequence Spread Spectrum (DSSS)• Frequency Hopping Spread Spectrum (FHSS)

Spread Spectrum Technology Direct Sequence Spread Spectrum (DSSS)

Spreads its signal by “expanding” the signal over a broad portion of the radio band

High bandwidth applications

Wi-Fi, video, OFDM, WIMAX

Ideal for higher bandwidth apps Up to 108 Mbps throughput

Spread Spectrum Technology

Frequency Hopping Spread Spectrum (FHSS)

Spreads its signals by “hopping” the narrowband signal using matching hopping patterns

Allows to be immune to noise

Reliable and secure

Ideal for lower bandwidth apps Up to 1.1 Mbps throughput

Hardwire vs WirelessConduit Design and Installation - Corridor

50 - 75 (2004)

0.02 (1999)

Cost is per mile. Includes boring, trenching, and conduit (3 or 4 inch). Cost would be significantly less for an aerial installation. In-ground installation would cost significantly less if implemented in conjunction with a construction project.

Twisted Pair Installation

11 - 15.8 (2004)

0.02 (1999)

Cost is per mile.

Fiber Optic Cable Installation

20 - 52 (2004)

1 - 2.5 (2004)

Cost is per mile for cable and in-ground installation. Cost would be significantly less for an aerial installation. In-ground installation would cost significantly less if implemented in conjunction with a construction project.

900 MHz Spread Spectrum Radio

8.2 (1999)

0.1 - 0.4 (2004)

Cost is per link.
